Power supply
The power supply is 24 V direct current. To improve the operating safety,
a redundant operating power supply consisting of two separate sources
can be used. For this purpose, you must connect the two supply voltages
to two different terminals of the 8-pin screw-type terminal block.Both
connections are uncoupled by means of diodes to prevent reverse voltage
supply or destruction through incorrect pole connection. There is no load
distribution between the sources. With redundant supply, the power
supply unit with the higher output voltage must supply the repeater alone.
Signal contact
A signal contact (relay with unconnected contacts) is used to signal
various disruptions in the repeaters. The signal contact is also connected
to the 8-pin screw type terminal block.
